Quantifying the Similarity of Two Coffee Bean Products by GC/MS and EDXRF

User Benefits

- By using the Smart Aroma Database™, trace aroma components that are difficult to detect in the Scan mode can be detected by the MRM mode. - EDX can be used to analyze minerals in foods either as is or by simple sample preparation.

Introduction

Coffee plays an important role as a drink. Coffee beans are produced mainly in South American countries such as Brazil and Colombia. These countries grow high-quality coffee beans in warm climates and rich precipitation. On the other hand, the countries that consume coffee are different from the countries that produce it. In Western countries, coffee culture is rich, and various coffee products (such as dark roast and latte art) are enjoyed. It is important for consumers to ensure the quality of coffee beans in both producing and consuming countries across geographical and cultural differences. To improve the quality and safety of coffee beans, elemental analysis should be conducted in addition to that of the texture, taste, and flavor. Coffee beans contain trace amounts of elements, but their effects are not small. For example, if there is a lot of iron in coffee beans, they may oxidize easily and deteriorate their flavor. Also, too much zinc and copper can have a negative effect on the body when consumed. In addition, toxic cadmium is easily absorbed from soil and water by plants, such as coffee trees, and can cause health risks if it accumulates in the body when ingested. In terms of taste and flavor, when metal containers and utensils come into contact with coffee beans, metal ions can leach out and change the flavor and quality of the coffee. For this reason, it is important to regularly inspect the elements contained in coffee beans to ensure that they meet safety standards. This application news presents two types of commercially available coffee beans measured using an energy-dispersive X-ray fluorescence spectrometer EDX-7200 and a gas chromatograph mass spectrometer GCMS-TQ8040 NX equipped with an AOC-6000Plus.
